Resistance Measurement
The B2985B/B2987B supports the resistance measurement up to 1000 P
(reference value).
Requirements Before turning the instrument on, connect cable, test leads, test fixture, and so on,
used for the measurement. See Figures 3-12 to 3-15 for connection examples.
The following accessories can be used.
• Triaxial cable, 200 V, 1.5 m
• Triaxial bulkhead connector, if needed
• High voltage test lead, 1000 V, 1.2 m, for High terminal
• Banana to lug cable, for connecting Common to chassis ground
• Banana to banana cable, for connecting Voltage Source High to Common
• Keysight N1414A High resistance measurement universal adapter
Instead of the triaxial cable and the triaxial bulkhead connector, Keysight N1415A
Triaxial to alligator clip cable, 200 V, 1.5 m can be used.
When turning the instrument on, leave the end of the measurement path open.
The following accessories are also available for high resistance measurement.
• Keysight N1424A/B/C Resistivity Cell
• Keysight N1425A/B Low Noise Test Lead, clip end
• Keysight N1427A/B Low Noise Test Lead, connector end, with bulkhead
connectors
• Keysight N1428A Component Test Fixture
To use the accessory, Keysight N1413A adapter is required. See Figure 3-11 for
connecting the accessory. Attach and connect the N1413A to the instrument, and
connect the accessory to the adapter which provides the connectors suitable for
the accessory. Always set the voltage source Low terminal state to FLOATING.
